  • This embodiment takes an EVDO network as an example to describe the method for improving user experience of a small flow user when multiple users compete for a resource.
  • a base station controller BSC periodically collects statistics on an average data transmission rate of a user terminal.
  • a value of the threshold may be set to 100 kbit/s, it can be determined that a user using the terminal is a small flow user, and a base station scheduling priority of the terminal may be improved. If the multiple users are all small flow users, their scheduling priorities are the same. A scheduling priority of the small flow user is relative to that of a large flow user. Definitions of the small flow user and the large flow user are determined according to their overall average data transmission rates.

  • the BSC may first collect statistics on an amount S Byte of data received or sent by the terminal within each statistical period T.
  • the statistical period may be set according to a factor such as a requirement of an operator, for example, 60 seconds.
  • R the statistics on the average data transmission rate of the terminal is collected, statistics on a downlink average data transmission rate may be collected, or statistics on an uplink average data transmission rate may also be collected.
  • Step 202 The BSC compares the average data transmission rate with a set threshold, and determines whether the average data transmission rate is smaller than the set threshold.
  • the BSC compares R obtained in step 201 with the set threshold, for example, 100 kbit/s, and may determine, according to a comparison result, whether a corresponding terminal user is a small flow user. If R is smaller than a value of the set threshold, it may be determined that the user is the small flow user; otherwise, the user is a large flow user.
  • the set threshold for example, 100 kbit/s
  • the small flow user is relative to the large flow user. Definitions of the small flow user and the large flow user are determined according to their overall data traffic.
  • the value of the threshold may be flexibly set and change dynamically, for example, may be flexibly set according to the factor such as the requirement of the operator. To make the implementation simple and convenient, a static threshold may also be used.
  • Step 203 The BSC sends a first priority adjustment command to a base transceiver station BTS if the average data transmission rate is smaller than the set threshold, where the first priority adjustment command carries information of adjusting a scheduling priority of the terminal to a high priority, and the BTS adjusts the scheduling priority of the terminal to the high priority.
  • a function of adjusting the priority of the terminal may be completed as follows:
  • the BSC sends the first priority adjustment command to the BTS, and the BTS executes the first priority adjustment command. If the average data transmission rate is smaller than the threshold, the BSC sends the priority adjustment command to the BTS, where the command carries the information of adjusting the scheduling priority of the corresponding terminal to the high priority.
  • the BTS receives the priority adjustment command sent by the BSC, and adjusts the scheduling priority of the corresponding terminal. Because the priority adjustment command received by the BTS carries the information of adjusting the priority of the corresponding terminal to the high priority, the BTS adjusts the scheduling priority of the user to the high priority.
  • a base station controller BSC first collects statistics on an average data transmission rate of a terminal, compares the average data transmission rate with a set threshold, and adjusts a scheduling priority of the corresponding terminal to a high priority if the average data transmission rate is smaller than the threshold, thereby solving a problem that a large flow user preempts a bandwidth resource of a small flow user when users compete for a resource on an access network, ensuring that the small flow user preferentially obtains a frequency band resource, and improving user experience of the small flow user.
  • the method may further include the following step.
  • Step 204 The BSC sends a second priority adjustment command to the BTS if the average data transmission rate is greater than or equal to the set threshold, where the second priority adjustment command carries information of adjusting the scheduling priority of the terminal to a normal priority, and the BTS adjusts the scheduling priority of the terminal to the normal priority.
  • a function of adjusting the priority of the terminal may be completed as follows:
  • the BSC sends the second priority adjustment command to the base transceiver station BTS, and the BTS executes the second priority adjustment command. If the average data transmission rate is greater than or equal to the set threshold, the BSC sends the second priority adjustment command to the BTS, where the command carries the information of adjusting the scheduling priority of the corresponding terminal to the normal priority.
  • the BTS receives the second priority adjustment command sent by the BSC, and adjusts the scheduling priority of the corresponding terminal. Because the priority adjustment command received by the BTS carries the information of adjusting the priority of the corresponding terminal to the normal priority, the BTS adjusts the scheduling priority of the terminal to the normal priority.
